The primary cause for the power increase was the design of an open porous membrane to both contain the liquid tin and allow transport of the fuel molecules. The wetting behavior of the liquid tin allows this. Although published data varies, the wetting behavior of tin has been experimentally determined by the authors to be poor in a reducing atmosphere.
